Antimony Resources Balances Resource Milestone and Deeper Discovery at Bald Hill

Antimony Resources releases deep high-grade antimony intercepts as SRK Consultants' first NI 43-101 resource estimate due by end of May, providing dual catalysts.

The Bald Hill antimony project in New Brunswick is approaching a moment that could transform it from a story of promise into one with hard numbers. While investors await the first NI?43?101 resource estimate from SRK Consultants, due by the end of May, Antimony Resources has released drill results that stretch the known mineralisation far deeper than previously thought. The combination of a definitive resource report and high-grade intersections at depth gives the project two distinct catalysts on a compressed timeline.

Drilling at Bald Hill has delivered some of the most eye-catching grades in the project’s history. Hole BH?26?10 cut zones containing 26.7% and 26.9% antimony at depths exceeding 350 metres, with one intercept coming from 495 metres below surface. That is a significant step beyond the shallow-focused earlier drilling. Meanwhile, hole BH?25?34 returned 4.38% antimony over 7.05 metres, including a higher-grade section of 9.76% over 3.15 metres. Updated 3D models now show the Main Zone extending more than 600 metres and open in all directions, with mineralisation reaching beyond 400 metres vertically.

The resource estimate from SRK Consultants is the technical linchpin. Originally scheduled for late April or early May, it has slipped slightly and is now expected by the end of this month. The work draws on 25,000 metres of definition drilling that was completed in the Main Zone by April 28, with samples processed at Activation Laboratories in Ontario. A previous technical report had flagged a conceptual target of roughly 2.7 million tonnes at grades of 3% to 4% antimony, but that figure was explicitly not a defined resource. The SRK report will be the first time the project’s geological potential is converted into a compliant, auditable number.

Operationally, the company is not waiting for the report to be published. A new phase of drilling began in the second week of May, comprising 13,000 metres of extension drilling in the Main Zone and another 6,000 metres testing three newly delineated targets: the Marcus Zone, the BH Central Zone and the BH South Zone. Since April 2025, Antimony Resources has completed more than 25,000 metres across 77 holes, and the ongoing programme is fully funded.

Parallel to the drill bit, Antimony Resources is laying the commercial groundwork. The company has engaged metal marketers to explore potential offtake agreements for future production, early-stage talks that could prove critical for project financing. The permitting process kicked off in April with GEMTEC Consulting Engineers and Scientists, and initial discussions have already been held with the provincial government of New Brunswick. A formal permit application is targeted around the turn of 2026/27.

The market environment offers a tailwind. China has suspended its export ban on gallium, germanium, antimony and superhard materials to the United States until November 27, 2026, though export licences are still required for overseas sales. The reference price for antimony sits at $51.80 per kilogram, roughly 172% above the level at the start of 2024. With China accounting for nearly half of global mine production and the US having no domestic antimony output since 2001, Bald Hill fits squarely into Western efforts to secure critical mineral supply chains for defence and electronics applications.

For now, the stock remains a leveraged play on drilling and technical milestones. After climbing 25.61% to C$1.03, it gave back 18.67% in a subsequent pullback; the last reported US closing price was $0.68. The next few weeks will bring three key inputs into the valuation: the SRK resource report, laboratory results from over 1,500 submitted drill-core samples, and details on the offtake discussions. If the high-grade drill hits can be translated into a robust resource base, Bald Hill will have a far stronger foundation for permitting, financing and eventual development.
